SPECIFICATION forming partiof Letters Patent No. 329,689, dated November 3, 1885.

, Application filed May lB, 188d.

, Beit known that I, WILLIAM J. TEMPLE, a

Maine, have invented a new and useful Swinging Churn; and I do hereby declare that the following is afull, clear, and exact description make and use the same. 1

My invention relates to an improvement in swinging churns of the class in which a rotary motion is imparted to the dasher-shaft by means of a pinion upon such shaft engaging with a stationary rack,and is fully illustrated in the accompanying drawing, which shows a front view of my invention with certain portions in vertical section indicated in the usual manner.

The object of my invention is to provide a churn that may be operated with as much regularity of motion of its parts as the nature of the case admits and with a minimum of effort to the operator.

My improved churn is constructed as follows: I provide a swinging frame, A A A G, for holding the vessel E, containing the cream, the

vessel E. I attach side pieces or straps, AA, extending upward, and preferably inclined inwardly toward their tops, where they are rig- The whole frame and the vessel or churn supported by it are designed to be swung backward and forward like a pendulum. To this end the frame may be suspended from any suitable support and attacheidto such support backward and forward. This may be accomplished in various ways, but the manner which I have adopted is more fully described hereinafter. From the top piece. G, of the frame a shaft or arbor, D, projects horizontally backward, fitting into and passing through a circular aperture in the hearing or backing B, and is keyed or otherwise secured in position on the backside of B. The part B is designed to afford a bearing for the shaft 'D, and may be of any convenient shape. It maybe made in the form shown in the drawing or extended downward, and so shaped as to allow the rack are of a circle.

B to be secured upon it. Journaled in the cross-pieces G and 0 is the shaft T,extendi'ng downward into the top of the churn E, where it is, detachably connected and engaged with the shaft T, carrying the dasher F E of the Upon the shaft '1, and preferably bechurn. tween the cross-pieces G and O", I fit the beveled pinion P, which may be adjusted and held in position by the hub m and set-screw n,- or, if desired, the pinion may he formed integral with the shaft. To the lower edges of bearing B, or when extended downward upon the face of B, or upon any proper backing or support, I attach the curved beveled rack B, so formed and placed as to engage with the pinion P. The rack B may be made integral with its backing or detach able therefrom. The shape of the curve of the rack is that of the The lower end of the shaft T is detaohably engaged with the shaft T of the dasher by the vertically-sliding sleeve 8 and set-screw t, or by any equivalent device, and the vessel 1*] is held upon the seat A by means of the set-screws t t, passing through the side straps, A A, or in any suitable manner.

The whole device may be suspended from brackets fixed to the side of the wall or to hooks from the ceiling, or upon a frame or horse, or in any convenient manner.

In operation the vessel E is supplied with cream, the dasher F placed in position with its shaft T projecting upward through an aperture in the cover 0 of the vessel E. The

shaft T is engaged with the shaft T, and the vessel E and the framein which itis suspended pushed sidewise, the whole swinging upon the shaft D. The pinion P, in el'igagement with the rack Realises the shaft T to revolve, and the shaft T carries with it in its revolution the dasher F F. Upon the return swing. caused by the weight of the apparatus and the contents of the vessel E, the revolution of the pinion P, the shafts T T, and the dasher F F is reversed. The swinging motion is continued until the churning is completed.

It is evident that by my invention the crea is subj ected to a continuous, even,and what may be called a compound motion, there being the motion from the swing of the frame and the simultaneous rotation of the dasher reversing with each oscillation. It must also be obvious that as the churn operates partly on the principle of the pendulum, moti'onh'aving been once communicated to it only the slightest force is thereafterward required to maintain the motion, and this irrespective of .the amount of cream churned 'at'one time.

As a convenient means of applying the force necessary to maintain the motion, I sometimes form an arm or lever, L, across the front of the side straps, A A. To one end of this arm I attach a cord and ring or staple and ring, e, through which the finger may be passed, and motion is then imparted to the whole by a simple up-and-down movement of the ha-nd.

To the opposite end of the lever L, I attach a weight, W, movable and adjustable by a setscrew, w, or other suitable device to assist the return swing of the frame.

My churn operates so easily that, once started, the weight of the hand alone,with scarcely a perceptible exertion of force, is sufficient to perform the operation of churning.

I am aware that churns swinging on the principle of the pendulum are not new, and that in such churns a rotary motion has been communicated to the dasher-shaft by means of' a pinion upon such shaft engaging with a the method of rotating the dasher shaft by means of a pinion upon the dasher-shaft engaging with such rack; but

It is hereby certified that in Letters Patent N 0. 329,689, granted November 3, 1885, upon the application of William J. Temple, of Hampden, Maine, for an improvement in Swinging Chums, errors appear in the printed specification requiring correction as follows: In line 29, page 1, before the words I attach, the words To two or more points upon A should be inserted; in line 54, page 1, the word into should be stricken out and the words to the top or nearly to inserted; in line 90, page 1, the reference letter '1? should be stricken out and the letter T inserted; and the reference letters a c 0" should be substituted for the reference letters 0 C 0" throughout the specification and claims, except in line 84, page 1; and that the said Letters Patent should be read with these corrections therein to conform to the papers pertaining to the case in the Patent Oflice.
